The loss cost Daley a coaching spot on “The Ultimate Fighter 12″ and a title shot with champion Georges St-Pierre.

The late blow, however, cost him any shot at a future in the UFC.

“He’s done,” White said after the event. “I don’t give a [expletive] if he’s the best 170-pounder in the world. He’ll never come back here again.

“There’s no excuse for that. These guys are professional athletes. You don’t ever hit a guy blatantly after the bell like that, whether you’re frustrated or not. It was probably one of the dumbest things I’ve ever seen because he is a talented guy, and he is one of the best 170-pounders in the world.”

Daley also is likely to face a suspension and fine, though Montreal’s athletic commission won’t rule on the matter for another couple days.

Koscheck, a four-time NCAA Division I All-American wrestler who also won a national championship, used takedowns and a stifling top game to win the decision. Even as they physically fought, Koscheck and Daley continued sparring verbally throughout the bout. The fighters both talked big heading into the bout and engaged in an intense staredown at Friday’s weigh-ins.

Following the bout’s conclusion, Daley got to his feet and tagged Koscheck with the cheap shot. Referee Dan Miragliotta immediately pinned him against the cage and chided the cheap shot.

“I don’t care if he fights in every show all over the world and becomes the best and everybody thinks he’s the best pound-for-pound best in the world, he will never fight in the UFC ever again,” White said. “He’s done.”

White said Daley offered little explanation for his actions other than to say he “didn’t hear the bell.”

Daley, a British fighter who previously competed with organizations such as Cage Rage and EliteXC, signed with the UFC in 2009 and entered the No. 1 contender’s bout with Koscheck after knockout wins over contenders Martin Kampmann and Dustin Hazelett. The loss to Koscheck snapped a four-fight win streak.
